{"product_id":"9781885696106","title":"Freshwater Mussels of Texas","description":"\u003cp\u003eFreshwater mussels of the family \u003ci\u003eUnionidae,\u003c\/i\u003e also known as naiads, have inhabited fresh waters around the world for the last 400 million years. Here in Texas, the presence of these unique mollusks ensures our water quality, helps support the worldwide pearl industry, and, in a quirk of history, influenced the founding of San Angelo. Yet their continued survival is by no means certain, due to overharvesting, environmental degradation, and the rapid spread of exotic mussel species.\u003c\/p\u003e\u003cp\u003eTo help professional biologists and amateur naturalists know and preserve these mollusks, this book provides baseline reference material for all 52 species of freshwater mussels in Texas. It focuses particularly on the unionids, with brief descriptions of other freshwater bivalves. A typical entry includes the following information:\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e Scientific and common names\u003c\/li\u003e\n\u003cli\u003e Distribution (with a range map)\u003c\/li\u003e\n\u003cli\u003e Size \/ Shell \/ Shell teeth\u003c\/li\u003e\n\u003cli\u003e External color \/ Internal color\u003c\/li\u003e\n\u003cli\u003e Soft tissues \/ Habitat \/ Spawning\u003c\/li\u003e\n\u003cli\u003e Glochidia \/ Hosts\u003c\/li\u003e\n\u003cli\u003e Economic importance\u003c\/li\u003e\n\u003cli\u003e Comments\u003c\/li\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003c\/ul\u003e\u003cp\u003eColor photos illustrate each species.
